John 18:14

"Now Caiaphas was he which gave counsel to the Jews, that it was expedient that one man should die for the people." Why doth the Evangelist again remind us of his prophecy? To show that these things were done for our salvation. And such is the exceeding force of truth, that even enemies proclaimed these things beforehand. For lest the listener, hearing of bonds, should be confounded, he reminds him of that prophecy, that the death of Jesus was the salvation of the world.

Josephus relates that this Caiaphas bought the high priesthood for this year. No wonder then if a wicked high priest judged wickedly. A man who was advanced to the priesthood by avarice, would keep himself there by injustice.

In order that, while our Lord was condemned by his colleague, he might not be guiltless, though his crime was less. Or perhaps his house lay in the way, and they were obliged to pass by it. Or it was the design of Providence, that they who were allied in blood, should be associated in guilt. That Caiaphas however was high priest for that year sounds contrary to the law, which ordained that there be only one high priest, and made the office hereditary. But the pontificate had now been abandoned to ambitious men.
